Free IVR Channel for testing

Hello,
I need to build demo of a bot, which we can call and talk with through the phone. I am looking for IVR channel that can be configured relatively easy and for free but:

  • Kore.ai IVR Sandbox seems to no longer provide phone number to call for testing
  • Twilio is not able to give me polish number which means some costs in terms of testing this bot (I would have to call Germany number and pay for it)

Does any1 have some idea how to get this done?

Resolved:

  • Kore.ai provided me with number after saving the channel. Still it was USA number so quite expensive to call from EU.
  • Twilio allows outgoing calls triggered by the API, this way German number calls me when i need it and I pay less. LINK
